If I was 30% or more on hard/sharp rock I'd be running Toyo M-55's or Nitto Exo-Grapplers. They're noisier on the Hwy but worth it for ruggediditty (technical term). As much as I generally don't like Goodyear, I do still miss the old Goodyear WorkHorse 10-Ply.

I can walk on water.......................but I do stagger a bit on alcohol.
